The Delta DVP20EH00T3 is a Main Processing Unit (Base Unit) in the DVP Series, a standard PLC from the EH2/EH3 family. It packs 20 I/O points on one base unit, sized for compact machine control where you need a self-contained controller without an expansion rack.
With 20 I/O points on the base unit, the DVP20EH00T3 fits applications where the I/O requirement is known and fixed — think a small packaging station, a pick-and-place cell, or a conveyor zone controller. That count is the total on-board mix; you size the base unit to match the sensor and actuator count, not the other way around.
